D. REISER PAMPHLET sTAcKER Oct. 19 1926.

Filed July 26. 1925 2 Sheets-Sheet 1 1 ,603,294 D; REISER PAMPHLET STACKER Oct. '19 1926.

Filed July 26 1923 2 Sheets-Sheet 2 trated in the draw1ng,'-drops on. its closed edge. As the pamphlet is deposited in the front end of the magazine, as illustrated in Fig. 1, the arms or fingers 16, which are 'mounted for movement upon the rock shaft .17 are swung to open or receiving position as shown in Fig. 1, by meansof camactuated roller 18 on the lower end of the lever arm 19 carried by shaft 1'?. The roller 18 is actuated by means of the cam 20 carried by shaft 20?, which shaft is operated from any suitable source of power through the gears. 20. The springs 21, which are secured at one end to the bottom ends of the fingers 16 and suitably anchored at their other ends in the frame work of the machine, normally tend to force the fingers 16 to 'closedposition as illustrated inFig. 2.

These fingers 16 work in the slots 23 provided in the edge of the plate2e which is suitably secured across the. frame of the machine The fingers 25 are also provided as a means of engaging-the lower portion are deposited in the magazine and moved to i of the front end of the stack of pamphlets which have already been stored in the magazine so as to maintain the same in such stacked position while the fingers 16 are swung to open position as shown in Fig. 1. Fingers 25 are carried by the strip 26 and are adapted to work up and down through openings in the plate 24. The strip 26 is actuated in its up and down nnvement by means of the lever arms 27 carried by rock shaft 30 which is actuated by the roller 31 carried by arm 31 which in turn is fixed on shaft 30. The shaft 30 is operated by means of the cam 32 fixed on the same shaft as cam 20. The endless belts 33, which receive the pamphlets as they are deposited in the magazine and serve to move the same slowly toward the rear end of the magazine, extend about the rollers 34 and 35 and are operated by means of the ratchet 36 fixed upon the shaft of roller 3st, The ratchet 36 is actuated by means of the pawl 37 carried by the shaft 17. This mechanism is so timed in its operation that each -lime a new pamphlet is deposited in the magazine the belts 33 are advanced one step so as to move the nest of pamphlets to the rear.

The present improvement, which I have embodied in the Ghristenson machine as above described, consists of a plurality of fingers 38 having downwardly extending curved portions 39' for engaging the upper portions of'the pamphlets as soon as they stacked position by the fingers 16. These fingers 38 serve to maintain the last deposited pamphlet closed'while the fingers 16 occupy open position for receiving the. next pamphlet,'as clearly. illustrated in Fig. 1. The fingers 38 which may be formed of any suitable metal are secured by means of bolt 40 and strap 41 to the plate 42 which in turn is screwed'on to the casting 43. The casting 13 is secured upon the rock shaft 44; by means of the set screw 45. The shaft 44 is supported in position by means of the bracketarms d6 which are provided'at their lower ends with the clamps 4:7 for engaging the. rear edge of the strip 18 extending across the frame of. the machine just below the magazine. Thus the supporting arms 46 can be readily attached to or detached from the machine by means of the clamping screws 4L9. Secured also to the rock shaft 4A is the lever arm 50 which provided with a series of pins 51 for engagement in the slot 52 inthe end of lever arm 53. The last named lever 53 has pivotal connection with one end of lever arm 54whose other end is fixedly mounted upon the shaft 30.

The parts are so constructed and arranged as to operate in the time relatior as above described, the'engagement of the pin 51 with upper end of the slot 52 causing the fingers 38 to be raised, that is upon lowering ofthe lever arm 53. Upon raising movement of the lever arm 53, the fingers will fall by gravity. By means of the series of pins 51 the extent or throw of the fingers 38 by the lever arm can be varied according to conditions. 7

Briefly stated the operation of my im proved attachment is as follows:

. At the time when the pamphlet is about to be deposited from the roller 8, the fingers 16 are in open position, as illustrated in Fig. 1, the rods or pins 25 occupy raised position so as to engage the lower, portion of the front end of the nest of'p'amphlets and at the same time the fingers 38 occupy lowered position so as to engage also the front end of the nest of pamphlets but at the upper portion of the same, so as to prevent the leaves of the pamphlet from falling open. Then as the pamphlet is deposited to the position illustrated in Fig. -1, the fingers 16 are automatically brought to closed position so as to place the pamphlet in closed condition against the front end of the nest of pamphlets in the magazine; and at the same time the pins25 are'lowered and the fingers 38 are raised to the position illustrated in Fig. 2 so as to permit such operation. Then the fingers 16 again move to open position and at the same time the fingers 38 arelowered to again occupy the position illustrated in Fig. 1, thereby completing the cycle of operations.

What I claim is 1. A stacking device, comprising ing magazine, means'for feeding articles of flexible sheet material in succession to said magazine soastostand on edge, and auto-.

matic means including a pivotally mounted article engaging portion for maintaining each article, upon being fed to said'magaa receivwith said articles as they are fed into said magazine. 1

2. A pamphlet stacking'device, comprismg a rece ving magazine, means for feeding pamphlets in succession. to said magazine, and automatic means including a pivotally mounted pamphlet engaging portion for maintaining each pamphlet closed upon being fed into said magazine, said maintaining means being freeof engagement with said zine. r

3. A stacking device, comprising a. receiving magazine, means for feeding pamphlets in succession to and depositing the open side of the same extending upwardly,

and automatic means for" engaging the upper part of each succeeding pamphlet 'so a's to maintain the sameclosed upon being fed intosaid magazine, said automatic means being free of engagement with said pain-Q phlets as they are fed into said magazine.

4. A stacking device, comprising a r eceiving magazine, means for, feeding pamphlets in succession to anddepositing the same in said magazine on edge with the open side of the same extending upwardly,

and automatic means for engaging the upper and lower parts of each succeeding pamphlet so as to maintain the same closed and in said magazine, the automatic'means for. en

gagement with the upper parts of said pamphlets being free of pamphlets as they zine. I
